Abstract
The utility model discloses a composite-lining fully-closed waterproof construction, which comprises an arch wall primary support, an arch wall waterproof plate, an arch wall secondary lining, an inverted arch primary support, an inverted arch waterproof plate, an inverted arch secondary lining and geotextile. The arch wall waterproof plate is disposed between the arch wall primary support and the arch wall secondary lining. The inverted arch waterproof plate is disposed between the inverted arch primary support and the inverted arch secondary lining. Preferably, both the arch wall waterproof plate and the inverted arch waterproof plate are self-adhesive polymer composite waterproof plates respectively adhered to the outer side of the arch wall secondary lining and the outer side of the inverted arch secondary lining. The composite-lining fully-closed waterproof construction is simple in structure, convenient in construction and reliable in quality. By the concept of skin-type waterproofing and full-ring arraignment of the waterproof plates, underground water can be prevented from seeping into a tunnel to flow away. The composite-lining fully-closed waterproof construction is applicable to tunneling works in underwater loss sensitive areas.
Description
Technical field
The utility model relates to the construction of tunnel structure, refers to the totally-enclosed water proof structure of a kind of composite lining particularly.
Background technology
Along with China is increasingly high to the attention degree of environmental protection, build the tunnel in underground water loss sensitive area, just need the consideration tunnel to build influence to environment, reduce to greatest extent because of building the influence that underground current mistake is brought in the tunnel.At present between Tunnel Second Lining arch wall and the preliminary bracing splash guard is set, builds in the tunnel in general area and can reach waterproof effect preferably; But, build if be used for the tunnel in rich groundwater area, then also exist following defective: splash guard only is arranged between secondary lining arch wall and the preliminary bracing, and underground water might overflow from inverted arch, causes that underground water runs off; Next is, the sealing that do not bond of splash guard and secondary lining, and water can stream between splash guard and the secondary lining external surface from the splash guard bottom under effect of water pressure, makes splash guard can not play waterproof action and then causes the underground water loss.
Summary of the invention
The purpose of the utility model is exactly will provide a kind of to solve because of building the totally-enclosed water proof structure of composite lining of the underground water loss problem that the tunnel causes.
For realizing above-mentioned purpose; The totally-enclosed water proof structure of the composite lining that the utility model designed; Comprise arch wall preliminary bracing, arch wall splash guard, arch wall secondary lining, inverted arch preliminary bracing, inverted arch splash guard, inverted arch secondary lining, geotextiles; Said arch wall splash guard is arranged between arch wall preliminary bracing and the arch wall secondary lining; Said inverted arch splash guard is arranged between inverted arch preliminary bracing and the inverted arch secondary lining, and its special character is: also be provided with the inverted arch splash guard between said inverted arch preliminary bracing and the inverted arch secondary lining, can prevent to cause that because of underground water overflows from inverted arch underground water runs off.
Preferably; Said arch wall splash guard and inverted arch splash guard are self-adhering-type macromolecule compound water-proof; Be bonded in the outside of arch wall secondary lining and inverted arch secondary lining respectively,, splash guard and secondary lining bonding be one through adopting self-adhering-type macromolecule compound water-proof.
The advantage of the utility model is: simple in structure, and easy construction, reliable in quality, the mode that splash guard is set through loopful between Tunnel Second Lining and preliminary bracing solves underground water and overflows from inverted arch, causes the problem that underground water runs off; Adopt skin-type waterproof theory; Through adopting self-adhering-type macromolecule compound water-proof; Splash guard and secondary lining bonding are the mode of one; Solution water under effect of water pressure can stream between splash guard and the secondary lining external surface from splash guard bottom, makes splash guard can not play waterproof action and then causes the problem of underground water loss.Tunnel structure also can be reached under the effect of water pressure prevent that underground water from infiltrating the requirement of tunnel and then loss.This structure is applicable to the construction of tunnel that is positioned at underground water loss sensitizing range.
Description of drawings
Fig. 1 is the structural representation of the totally-enclosed water proof structure of a kind of composite lining.
Among the figure: arch wall preliminary bracing 1, arch wall splash guard 2, arch wall secondary lining 3, inverted arch preliminary bracing 4, inverted arch splash guard 5, inverted arch secondary lining 6, geotextiles 7.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail, so that colleague technician's understanding:
The totally-enclosed water proof structure of composite lining shown in the figure comprises arch wall preliminary bracing 1, arch wall splash guard 2, arch wall secondary lining 3, inverted arch preliminary bracing 4, inverted arch splash guard 5, inverted arch secondary lining 6.Through loopful compound arch wall splash guard 2 of self-adhering-type macromolecule and inverted arch splash guard 5 are set, and arch wall secondary lining 3 and inverted arch secondary lining 6 are reached totally-enclosed waterproof effect with arch wall splash guard 2 and inverted arch splash guard 5 bondings for the mode of one respectively.After arch wall preliminary bracing 1 and inverted arch preliminary bracing 4 constructions finish; Lay the compound inverted arch splash guard 5 of self-adhering-type macromolecule at inverted arch; Inverted arch splash guard 5 land sides are tack coat, build inverted arch secondary lining 6, and inverted arch splash guard 5 tack coats and inverted arch secondary lining 6 structures are combined into one.After finishing, 6 constructions of inverted arch secondary lining hang the ring longitudinal seam of compound arch wall splash guard 2 of self-adhering-type macromolecule and appropriate welding arch wall splash guard 2, inverted arch splash guard 5; Geotextiles 7 is set to prevent that effectively the first-class object of anchor pole reinforcing bar is to the infringement of arch wall splash guard 2 in the arch wall preliminary bracing 1 between arch wall preliminary bracing 1 and arch wall splash guard 2; Build arch wall secondary lining 3, arch wall splash guard 2 and inverted arch splash guard 5 are combined into one with arch wall secondary lining 3 and inverted arch secondary lining 6 respectively.Thereby form a totally-enclosed water proof structure of composite lining.
